Agisoft Metashape software is quite familiar in the surveying world and is used for its features as well as the safety and accuracy of geodetic data. Agisoft Metashape is software used to process and transform images taken by unmanned aerial vehicles for the purpose of collecting image data into 2D, 3D spatial data as required in the work. geodetic.

Basic introduction of Agisoft Metashape software

Agisoft Metashape is software used to process and transform images taken by unmanned aerial vehicles for the purpose of collecting image data into 2D, 3D spatial data as required in the work. geodetic.

Agisoft Metashape professional software processes digital images, creates 3D spatial data in the form of point clouds, digital models and merges snapshots to create orthogonal images Besides, the software also has functions like adding visual effects, making indirect measurements of objects at various scales.

Agisoft’s applications are used in areas such as: GIS geospatial information, preserving architectural cultural heritage and supporting the making of scale maps.

Application of Agisoft Metashape software in geodetic data processing

Triangular photometric method

• Process different types of images: aerial (nadir, oblique), close range, satellite.
• Auto correction: frame (including fisheye), spherical and cylindrical camera.
• Supports multi-camera projects.
• Scanned image with fiducial mark support.

Editing and grading point clouds

• Build edit models for accurate results.
• Automatic multi-layer point classification for further reconstruction customization.

Digital elevation model: DSM/DTM . format

• Digital Surfaces and or Digital Terrain Models – depending on the project.
• Geo-referencing based on EXIF/flight log meta data, GCP data.
• Support EPSG registered coordinate system: WGS84, UTM, etc.
• The longitudinal data are configurable based on geoid undulating grids.

Geo-referencing visuals

• Georeferencing visualization: GeoTIFF format most compatible with GIS; KML files will be placed on Google Earth.
• Export in batches for large projects.
• Color correction for uniform texture.
• Shading filters are available to combat artifacts caused by moving objects.
• Custom planar and cylindrical projection options for close-up projects.

Terrestrial laser scanning (TLS) registration

• Simultaneous adjustment of both laser scanner and camera positions.
• Ability to combine TLS and optical depth maps.
• Automatic target detection and marker support for manual alignment of scanner data.
• Masking tools to ignore unwanted objects in the scanner data.

Ground control point

• Enter GCP ground control points to georeference and control the accuracy of results.
• Automatically detect encrypted/unencrypted targets for fast GCP import.
• Scale bar tool to set the reference distance without performing device positioning.

Measurements: distance, area, volume

• Instruments are available to measure distances, areas and volumes.
• For more complex data analysis, the products of optical image processing can be smoothly transferred to external tools thanks to a variety of export formats.

Stereometric measurement

Professional 3D display and 3D controller support precise and convenient stereoscopic vectors for measurement purposes and features.

3D modeling: create and texture

• Various scenes: archaeological sites, artifacts, buildings, interiors, people, etc
• Upload directly to various online resources and export to a variety of popular formats.
• Real photo textures: Supports HDR and multi-file (including UDIM layouts).

Create panoramas

• 3D reconstruction for data captured from the same camera location – camera station, provided there are at least 2 camera stations.
• 360° panorama stitching for single-camera data.
